15+ 20 ÷ 5

Is

15 + 4= 19 or 5 ÷ 5=9

210-5 x 30

Is it

210-150=60 or 205 x30=61590

Have you heard of BEDMAS?

it shows the correct order of operation in arithmetic

B-brackets first

E-exponents

D

M ...Division and Multiplication in the order they come

A

S ... Addition and Subraction in the order they come

so for your first one it is

=15 + 4

=19
